A Precise Determination of ${\alpha }_s$ from the Heavy Jet Mass Distribution

Miguel A. Benitez, Arindam Bhattacharya, Andre H. Hoang +4

A global fit for ${\alpha }_s(m_Z)$ is performed on available $e^{+}{e}^{-}$ data for the heavy jet mass distribution. The state-of-the-art theory prediction includes $\mathcal{O}({\alpha }_s^3)$ fixed-…
